THE EXPERIMENTAL AND NUMERICAL STUDY OF THE FORCES DURING THE INCREMENTAL FORMING OF TITANIUM SHEETS

Incremental forming is a rapid prototyping process that allows sheets to be formed without using tools, numerically controlled machine tool. A wide variety of shapes can generated with this process. The objective work study through experimental tests and numerical simulations the behavior ASTM grade 2 titanium during incremental point (SPIF). Spinner MFG850 machining center from ISET in JENDOUBA coupled multi-component force sensor FN7325 was used for thin by As diameter punch its movement are parameters having direct effect on force, diameters punches dp varying between 10 15 mm various paths made up circular movements horizontal plane have been carried out experimentally. Numerical simulation large elastoplastic deformations ABAQUS/explicit. Comparisons evolution different values displacement step ∆zare out.
